Just for similar-implementation-ideas, flvplayer simply aligns the poster
image to the upper-left of the object element, with no scaling at all. If
width and height are not given, it simply doesn't display at all.
Unless there's already some alternate intent, I suggest <video> scale to the
poster's size if no explicit size is given.
